Patented. Dec. 29, 1903.

Application flied November 26, 1907. Serial No. 403,922.

To all whom it may concern:

Be it known that I, FRANK G. Cnnrsrnn sun, a citizen of the UnitedStates, residing at Pacific Grove, in the county of Montcrey, State ofCalifornia, have invented certain new and useful Improvements I inFolding Umbrellas; and I-do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in theart to which it appertains to make and use thesame...

This invention relates to folding umbrellas and has for its primaryobject to provide an umbrella of thistype which, while simple-in itsconstruction, will be thoroughly practical and may be readilymanipulated. The novelty in the umbrella resides princi- I pally in thespecific form of ribs employed and in the manner in which they are to befolded and in which they are held against fold ing when the umbrella isin use or is folded in the ordinary manner.

In the accompanying drawings, Figure 1 is a sectional view through theumbrella, the same being unfolded, Fig. 2 is a detail perspective new ofone of the ribs showing in full lines the sections partly folded and indotted lines their relative folded. I

As shown in the drawings, the staff of the umbrella is comprised of apair of sections one positions when unof which is indicated by thenumeral 7 and the other by the numeral 8, the sections 7 being providedwith the usual ferrule 9 and the section 8 with the usual handle 10. Inorder that these two sections may be disconnected when it is desired tofold the umbrella, the section 7 has one of its ends reduced andthreaded as at 11 and the other section 8has its corresponding endformed with a threaded bore 12 in which the reduced threaded end of thesection 7 is received.

Fixed upon the section 7 of the umbrella staff is a head 13 which is ofthe usual construetion and to which are pivoted the upper ends of theribs of the umbrella which ribs .are indicated in general by thereference character A. Slid able upon the staff is a runner 14 to whichthe inner ends of the stay ribs of the umbrella frame are pivoted andthis runner comprises the usual sleeve portion and head 15 which isprovided with a number of slots 16 in which the said ends of the stayribs are pivoted.

Each of the main ribs of the umbrella comprises a pair of sections oneof which is indicated by the numeral. 1.7 and the other by the numeral18, the section 17 being the uper section and the section 18 the lower.Both of these sections are of the usual chan nel construction and thesection 18 is of slightly less width than the section 17 and is pivotedthereto by means of a pivot pin 19 which is passed through 20.formedintegral with the two sections at their connected ends. Fixed, in anysuitable manner, upon the section 18 of each rib is a finger 21 andloose u on each of the sections 17 is a sleeve 22 whic 1, when thesections are in normal posit-ion, or in other words, are unfolded, isdesigned to he slid over the corresponding finger and hold the saidsections in such position, it being understood, of course, that when thesections are in this position, the fingers of the sections '18 lieagainst the sections 17.

-The stay ribs of the'i'rame are indicated by the numeral 23 and arepivoted to the main ribs and the runner 14 in the usual manner.

What is claimed, is

A'n umbrella rib comprising a pair of sections, each of the sectionsbeing of channel formation and being cut away to form a pair of carswhich project beyond the upper surface of the corresponding section, theears of one section being pivoted to the ears of the other, a fingerfixed in the. channel of one section and receivable in the channel ofthe other sectlon when the rib sections are in ahnement, and a sleeveupon the last mentioned section, said sleeve being movable to inclosesaid finger.

In testimony whereof, I aflix my slgnature, 1n presence of twowitnesses.

FRANK G. CHRISTENSEN.
